The Leafs like Brennan, as he enjoyed a tremendous AHL campaign with the Toronto Marlies in 2013-14. Therefore, the decision to bring him back is understandable. Still only 25, he may have an NHL future when all is said and done.

What does it give the Chicago Blackhawks?

In Abbott, the Blackhawks receive a diminutive AHL scorer with very limited NHL upside (if any). Chicago has depth on defense, so moving Brennan makes some sense. That said, this was largely a swap of minor leaguers.

Fantasy Impact

Brennan may still have a bit of fantasy value if he can make it back to the NHL on a permanent basis, though that's still a long shot. As for Abbott, he is not expected to see much NHL time during his stint in the Chicago organization.
